UNITED STATES I CHARLES W. MEASON, OF WALNUT, KANSAS, ASSIGNOR OFONE-HALF TO JAMES M. GOFF, OF SAME PLACE.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 273,871, dated March13, 1883.

Application filed January 18, 1883. (No model.)

To all whom it may concern 7 Be it known that I, CHARLES W. MEASON, acitizen of the United States, residing at Walnut, in the county ofCrawford and State of Kansas, have invented a new and useful Nut- Lock,of which the following is a specification, reference being bad to theaccompanying draw lugs.

This invention relates to nut-locks for railroad fish-joints and forother purposes where it is desirable or necessary to secure nuts againstworking loose by the shaking of the parts to which they are attached;and it has forits object to provide a simple and con venient r5 device,which may be readily applied or detached, as will be herein-after fullydescribed, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is a perspective view, showingmy improved 2o nut-lock applied to a railroad fish-joint Fig.

2 is-a horizontal sectional view of the same.

The same letters refer to the same parts in both figures.

Ain the drawings designates the rail, B the fish-plate, C the bolt, andD the nut, all of which are of the usual well-known construction.

E is a Hat spring, which is bent so as to form two leaves, F G, thelower one of which, F, 0 which is the shortest, is provided near its endwith a. perforation, H, to receive the bolt, upon which the saidspringis adjusted in such a manner that its upper leaf, G, shall extendover the said bolt and terminate between the nuts of two adjoiningbolts. Between the said 5 nuts, which are screwed down tightly, isplaced a block, K, the ends of which may be either square orheveled, soas to abut against the sides or edges of the nuts, which are therebyprevented from turning. The face of the 4.0 block K has a longitudinalgroove or recess,

L, to receive the end of the upper leaf of the spring E, which serves tohold the said block securely in position, the spring itself being heldby the nut upon the bolt upon which it is adjusted. When desired, bysimply releasing the pressure of the spring, the block K maybe easilyremoved for the purpose of permitting the nuts to be unscrewed.

I claim as my invention and desire to secure by Letters Patent of theUnited States- In a nut'lock, the combination, with a flat spring bentso as to form two leaves of unequal length,the lower short one of whichis provided with a bolt-hole, of a block having a longitudinal groove orrecess to receive the end of the upper spring, substantially as setforth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

CHARLES WILLIAM MEASON.
